the other end (rotating clockwise is good for cleaning).
4) Gently rotate the cleaning rod for a circle, and keep rotating it when drawing it out.
5) Use a dry cleaning rod to do the action in step 3 and 4. Note: do not touch the soft end of
the cleaning rod.
6) Clean the pin in the port of connector according to the following steps:
z
Drip a drop of isopropyl alcohol onto the nonlinting cloth, Gently wipe
the connector and the pin.
Key prompt:
If use too much isopropyl alcohol or let it evaporate randomly (about 10 min),
residual may be left. Avoid the bottleneck touching the cloth to make the surface
dry rapidly.
z
Gently wipe the same surface with a dry nonlinting cloth to ensure the
connector and the pin completely drying.
z
User can use a portable optical fiber microscope or detector to inspect
the surface of the optical connector.
7) Install the connector of optical interface back to the instrument (push and rotate it
clockwise).
8) Discard the cleaning rod and cloth after using once.
9.3 Maintenance and Changing of Battery
OTDR series optical time-domain reflectometer adopts inlaid rechargeable lithium battery.
Maintaining battery should pay attention to the follows:
● You’d better store the instrument (including battery) under room temperature
(15℃ to 30℃), and place it at dry place to keep its best performance.
● If the instrument is left unused for a long term (leave unused for more than 1
month), you’d better charge the battery once a month.
● Do not charge the battery too long (exceeding 8 hours), otherwise the battery
may be damaged;
● Battery changing operation steps are as follows:
a) Take down the cover of battery storage;
b) Firstly, move the rechargeable battery away, then, draw out the battery
connector from the plug hole of the rechargeable battery.
9.4 Calibration of OTDR Products
We calibrates the product according to ISO/IEC
17025 standard. The standard regulates
that the calibration file can exclude the recommended calibration interval, unless otherwise
achieved agreement with customer.
The effectiveness of regulations depends on the operation conditions. For example, the
effectiveness of calibration can be prolonged or shortened according to the using intensity,
environmental conditions and equipment maintenance. Please confirm the proper equipment
calibration interval according to the demands of accuracy.
Under the condition of normal using, We recommends recalibrating the equipment every
three years. Equipment calibration work needs to be conducted in manufacturer’s factory.
